They can likely pair Jax and Diaw for at least one good player. If they really want to overhaul they could package Augustin or Nazr in the deal too.
This team needs to stay away from shitty contracts like Deng. It's one reason why they're in the mess they're in. Diop, Carrol, etc. Not to mention that Deng is inconsistent and injury prone. A big fat no to him.
